Amputees can control their bionic prosthetic limbs with their minds, thanks to tiny implanted myoelectric sensors (IMES) developed by Icelandic orthopedics company Ossur and surgically placed in a patient’s residual muscle tissue.
Ossur implanted tiny sensors in the residual muscle tissue of two amputees that they say trigger movement in the prosthesis via a receiver. Ossur President & CEO Jon Sigurdsson was due to announce in Copenhagen on Wednesday (May 20) that the two amputees are the first world-wide to be able to control their lower-limb prostheses subconsciously. 
One of the patients trialing the new implants, Gummi Olafsson, lost his right foot and lower leg years after a childhood traffic accident. He said the implants allowed him to control his bionic leg and foot almost instantly.
“As soon as I put my foot on, it took me about 10 minutes to get control of it. I could stand up and just walk away. Come back, sit down, use my muscles to move my foot in the position I wanted to use it. It was, like you couldn’t believe the feeling when you were moving your ankle. It was really strange. I couldn’t explain it. It was like, I was moving it with my muscles, there was nobody else doing it, the foot was not doing it, I was doing it, so it was really strange and overwhelming,” Olafsson remembered.
